2. Safety
Proper Storage of Grain Bin/Silo Materials Prior to Construction
Wet storage stain (rust) will develop when closely packed bundles of galvanized material, such as sidewall and roof sheets, have moisture present. Inspect roof and sidewall bundles on arrival for any moisture. If moisture is present, it must not be allowed to remain between the sheets. Separate the sheets or panels immediately and wipe them down. Spray with a light oil or diesel fuel.
If possible, sidewall bundles, roof sheets and other closely packed galvanized materials should be stored in a dry, climate controlled building. If outdoor storage is unavoidable, the materials should be stored so that they are raised above the ground and vegetation. Any stacking and spacing materials should not be corrosive or wet. Be sure to protect materials from the weather, but permit air movement around the bundles if possible.
Storing roof bundles and sidewall sheets at a slight incline can also help minimize the presence of moisture. Storing the bundles with the center of the dome up (like an arch) is one option for minimizing moisture during storage. Sidewall bundles can also be stored on edge but must be secured so that they do not fall over and cause injury.
If “white rust” or “wet storage stain” occurs, contact the manufacturer immediately about ways to minimize the adverse effect upon the galvanized coating.

4. General Information

Bulk Feed Tank Assembly Manual General Instructions
This product is intended for the use of storing feed only. Any other use is a misuse of the product. While every effort has been made to keep the edges from being sharp, please wear the proper protective
clothing while erecting the Bulk Feed Tank. Our company recommends that you contact the local power company and have a representative review
the installation so the wiring will be compatible with their system and so that you will have adequate power supplied to the unit.
A Bulk Feed Tank weighs a minimum of 444 lbs. (201 kg). All precautions should be taken when raising the tank to its feet. Follow the instructions given later in this manual.
The safety pages show you where you can find the safety decals. The photographs show exactly where the decals should be. If a decal has been damaged or is missing contact our company for a free replacement.
First, read the assembly manual completely before starting to assemble the Bulk Feed Tank. Check the shipment with the packing list to be sure there are no shortages.
1. Decal protective mask must be removed when assembling tank. Mask may become difficult to remove if left exposed to sunlight.
2. Vertical seams must be staggered on all sidewall rings.
3. When legs extend up 2 rings, the leg holes must be in alignment in the bottom 2 rings.
4. All hopper seams and the hopper collar use truss head bolts. The heads of the bolts must be on the inside of the tank.
5. Hex head bin bolts are used on all sidewall and roof seams with the bolt heads on the outside of the bin.
6. Hex head bolts are to be used on all leg to sidewall connections with the bolt heads on the inside of the tank.
7. All bolts are to be tightened from the nut side only. Do not allow bolt heads to spin.
8. Drift punches can be used to align holes.
9. All vertical sidewall sheet seams must be overlapped in the same direction.
10. A hole spacing of 3-1/8" is used at the top of all top sidewall sheets and at the bottom of all bottom sidewall sheets.

4. General Information
Selecting the Proper Site
The selected site should be level, firm and free from underlying debris. The tank can be installed satisfactorily on slopes, but as the slope increases, additional labor and materials are required for the foundation. The concrete foundation surfaces must be level and tamped thoroughly to prevent uneven settling from the weight of the tank. Good water draina ge should be provided to prevent water collecting under or around the tank. The site mu st allow conve nient access for loading and unloading and plus provide additional space for future units. Also, consider the positioning of handling equipment, availability of electricity, etc.
. If some fill is required, it should be watered
Tools
Tools recommended for assembly of Bulk Feed Tanks.
1. Assorted sizes of combination wrenches
2. Hammer
3. 3-12" Long drift punches

How to use charts on this page
The chart titled “Body Sheet Chart” is for the reference when building the tank. This chart tells you how many rings the specific tank must have. To read the chart find the tank size you wish to build. For example, an 12' diameter tank with 4 rings will look like BFT 12'-4 rings. The side labeled “Gauge” will tell you which body sheets to use. The sheets are color coded, simply match the gauge number with the color. (Use “Sheet Gauge Color Code Chart” on Page 27.)

Sidewall Erection
12'-21' Bulk Feed Tank
12'-21' Diameters Bulk Feed Tanks are designed to be built vertically utilizing bin jacks or a crane of adequate capacity. Before bolting the sidewall sheets together, check that you have the proper gauge steel for the first ring. The higher gauge number denote the thinner materials. For example, 20 gauge material is thinner than 14 gauge. In erecting all Bulk Feed Tanks the thinnest material always goes on top, therefore the first sidewall ring you assemble will be the top ring of the tank. Check the various gauges of the tank with the color code chart and begin building accordingly. Remember assemble th e top ring first. Note ring overlap detail in Figure 6B.
NOTE: See Page 27 for proper gauges and color code chart. IMPORTANT: The number of rings shown for each tank size are maximums. (15' 60° Tanks have a
6 ring maximum, 21' 45° tanks have a 7 ring maximum. 12' 60° Tanks have a 7 ring maximum. 15' 45° Tanks have an 8 ring maximum. The 12' 45° and 18' 45° tanks have an 9 ring maximum.)

IMPORTANT: BEGIN BOLTING IN THE CENTER OF SHEETS when connecting sidewall rings to one
another. When bolting sidewall rings to one another, always begin bolting in the center of the sheet and work toward the outside edges (horizontal seams). This allows the sidewall to draw up evenly.

A Left Panel B Right Panel C Sidewall Sheet
Once you have selected the proper gauge material, begin assembling all sidewall sheets in the following manner. Standing on the inside of the tank, place the left panel to the inside with the right panel to the outside.
NOTE: The rope caulking is applied before each sheet is assembled. Wipe sheets clean where caulking
will be applied. Apply caulking on each side of the holes of the vertical seams and on each side of the horizontal row of holes.
Using correct size bin bolt throughout, begin assembling sidewall sheet end to end (overlapping the same way throughout) until the ring is completed. All body sheet bolts are to be installed with the bolt head and its neoprene washer to the outside and the nut to the inside. Do not tighten bolts until all sheets are assembled and form a complete ring. Remember to attach lifting straps at the bottom of the vertical seams while bolting the sheets together. These straps, coupled to the jacks, will enable you to later elevate the tank. Now tighten the bolts, in sequence, starting from the center and working to the edge in both directions. This permits the sidewall sheets to draw-up evenly. Complete one ring and stop. You are now ready to assemble the roof.

15' and 18' Roof Assembly Instructions
After completing first ring assembly, you are ready to begin roof construction. First, build a roof center support to hold the peak ring in place at the proper height. A simple structure consisting of a sturdy cross arm attached to a pole and supported by a platform or scaffo lding will do. Stand the center support directly in the center of the tank. The bottom of the peak ring should be 89-5/16" (2269 mm) above the foundation on the 18' tank and 78-15/16" (2005 mm) above it on the 15' tank. These dimensions are approximate ones used in BFT construction. Adjusting the center support height will ease roof erection. Refer to the accompanying drawings for details. Install six (6) roof reinforcement angles spaced equally around the tank. Reinforcement angle edges are parallel with sidewall sheet and peak ring, see views “A-A”
on Page 36 and “D-D” on Page 37.
The reinforcement angles utilize every other hole in the peak ring. At the sidewall, there are twelve (12) spaces between each reinforcement angle on the 18' tank and ten (10) spaces between each on the 15' tank. Next, “skin” the roof by installing the roof panels on the just completed reinforcement structure. Reinforcement angles will share all roof panels holes, including hole where panel and peak ring attach. Ensure that all roof seams are caulked and lapped correctly as shown in the accompanying detail drawings.

A Anchor Cable B Anchor Jacks Securely
Anchor Tank Before Second Ring Assembly
Anchor all jacks securely with metal stakes and cables (use one jack per sidewall sheet). Now raise the tank just enough to assemble the next ring. When lifting the tank crank all jacks at an equal rate. This will prevent bowing previously assembled rings and make for easier hole alignment. To the inside of the first ring bolt the next ring. Be sure to stagger the sheets and select the proper gaug e material. Lower the tank on the foundation after assembling and tightening bolts on each new ring. Now re-bolt lifting straps t o the lowest ring in place thus far.
NOTE: Add outside ladders and other accessories to tank walls as you continue to raise the tank. After body sheets are assembled and bolts are tightened, raise the tank and attach the legs. Do not put a
bolt in the bottom sidewall hole yet, because the hopper must be attached here. When the legs are in place and tightened, release the jack enough to rest the tank on the legs.

Roof Ladder Support Bracket Installation
The roof ladder requires support brackets at the top of the ladder. These upper ladder support brackets either bend in towards the center of the ladder or bend out away from the ladder depending on the diameter and roof angle of the tank being assembled. See Figure 8D below and Figure 8I on Page 47 that show brackets for the 12'-30° and 12'-40° roofs. See Figure 8E on Page 44 and Figure 8J on Page 47 that show brackets for 15'-30° and 15'-40° roofs. See Figure 8F on Page 45 and Figure 8K on Page 47 that show brackets for 18'-30° roofs. Assemble the wedge and support brackets to the ladder rail as shown in Figure 8G and Figure 8H on Page 46. Then, slide the support bracket assemblies along the ladd er rails as shown in Figure 8D below, Figure 8E on Page 44 and Figure 8F on Page 45 until the slots match up with the pre-punched holes in the roof panel and attach using the existing bolts.
NOTE: The roof ladder supports must be assembled so that the maximum distances are not exceeded.
See Figure 8L on Page 48 and the “maximum distances chart” to determine maximum allowable

Ladder System With Safety Cage
Extension Rail Installation
Before the safety cage can be installed, the ladder extension rails must be attached. Start by bolting the spacer brackets through the top and bottom set of holes in the top ladder section. Then, attach the extension rail to the spacer brackets as shown in Figu re 10 A. When installed correctly, the bottom of the extension rail should be flush with the bottom of the top ladder section. Use 5/16" x 1" bin bolts for all connections.

Eave Adjustable Braces
The adjustable braces must be attached at this time. A large diameter tube and two (2) smaller tubes are used to make up one adjustable brace. Slip the smaller tubes inside the larger tubes and attach one smaller tube to the top of the ladder extension rail. Adjust the other smaller tube so the bottom of the flattened tube reaches the roof panel. Field drill four (4) 5/16" holes through both large and small tubes and bolt together using 1/4" x 1-1/2" bolts and nuts. This prevents the adjustable braces from slipping.
(See Figure 10B.)

Safety Cage Hoop Assembly
To complete the safety cage hoop installation, some pre-assembly is required. Attach four (4) safety cage brackets to the extension rails and two (2) safety cage brackets to the second 4' ladder section as shown in Figure 10C. See cage hoop bracket detail on Page 63 for proper installation. Next, bolt each set of safety cage hoop halves together using 5/16" x 1" bolts with the head of the bolt to the inside of the safety cage. You may now bolt these assemblies to the safety cage brackets. Tighten bolts as you go.

When starting to attach hopper sheets to sidewall it is recommended that the first hopper sheet seam be positioned halfway between leg positions. Lap the hopper sheets as shown in Figure 12A. Apply two (2) strips of caulking on all seams at sidewall to hopper and hopper sheet to hopper sheet. Use 5/16" x 1" bin bolts (head to outside of tank) for attaching hopper sheets to bottom sidewall sheet. Use truss head bolts to attach hopper sheet to hopper sheet. Be sure to place the head of the truss head bolt on the inside of the hopper. Leave one hopper sheet out to allow room to install the hopper collar. Be sure to use two (2) strips of caulking between hopper collar and hopper sheets, then put last hopper sheet in place. After the collar is in place, attach the hopper braces and tighten all bolts.

14. Raising Bin

Make sure there is enough clearance between the tank and surrounding power lines, electrocution may occur.
All usual and customary precautions must be taken to ensure safety of personnel and property.
NOTE: Leg shims are not standard equipmentand must be obtained locally.
Raising Bin to Set on Foundation
Be sure that all bolts are tightened properly. The Bulk Feed Tank can now be set up on foundation. A crane of adequate capacity attached to a spider assembly with cables connecting at each vertical sidewall seam just above the legs will usually do the job. Reference a qualified rigger.

Roof Panel
Identical pre-punched roof panels are available from the GSI for inlet and outlet sections of pneumatic fill systems. Extruded lip of the panels provide for weather-tight installation. Caulking placed between angle rings virtually eliminates all leakage problems. Rubber seal must be utilized at roof cap area to prevent material “blow by” from pressurized systems.
To install fill kits in roof panels not pre-punched, cut 5-5/8" (143 mm) diameter holes in opposing roof panels as shown. Caulk sufficiently to provide weather-tight seal.
Refer to PNEG-1904, that is included in the pneumatic fill kits for information on installation of the cap latch and lid sealing components.
